Try these steps in order:
- Update Office

- Test in Safe Mode
- Select Search, type Run, and open Run.
- Try these commands one at a time:
- winword /safe
- excel /safe
- powerpnt /safe
- Make sure there is a space before /safe.
- If the app opens in Safe Mode, the issue is likely caused by an add-in.
- Disable add-ins if Safe Mode works
- In the Office app opened in Safe Mode, go to File > Options > Add-Ins.
- In the Manage list, select the app’s add-ins or COM Add-ins, then select Go.
- Clear one add-in, select OK, then restart the app normally.
- Repeat until the problem add-in is found.
- If files open in the wrong app or do not open by double-clicking
- Open Control Panel > Programs > Programs and Features.
- Select the Office product > Change > Quick Repair.
- If needed, manually set the correct default app in Control Panel > Programs > Default Programs.
- If a specific document is damaged
- Open Word, Excel, or PowerPoint.
- Go to File > Open > Browse.
- Select the file, choose the arrow next to Open, then select Open and Repair.
If Word, Excel, and PowerPoint all fail to open, Online Repair is the best next step.
